Field Crops, Forage and Turfgrass Production
-
2022 plant disease losses, including control costs, amounted to an estimated $933 million. The value of the crops used in this estimate was approximately $8200 million, resulting in a 11.4% relative disease loss across all crops included in this summary. The estimated values for most crops used to compute these disease losses are summarized in the UGA Center for Agribusiness & Economic Development 2022 Georgia Farm Gate Value Report (AR-24-01). Some estimates for fruits, ornamentals, and turf rely on Extension specialists’ knowledge of the industry and industry sources for information.

Baleage Production and Use
Implementing a baleage system takes consideration and planning. Producers need to weigh the benefits, challenges, and costs to optimize their forage production and livestock feeding operations. Baleage does have additional costs associate with it—including a wrapper, plastic, and plastic disposal. It also takes different management strategies to store and feed baleage to prevent spoilage when compared with traditional dry hay. Despite some additional management challenges, baleage can be very beneficial for many producers. It has higher forage quality when compared to dry hay harvested under the same conditions and is highly palatable to livestock. Finally, using baleage as a forage harvesting tool can reduce risks of forage loss due to weather and promote forage harvest on a timely harvest interval.

How to Use a Grazing Stick
Grazing management requires accurate estimates of forage availability to adjust forage supply to meet animal needs. However, incorrect forage availability estimates can negatively impact important grazing-management decisions such as stocking rate and grazing time. Visually estimating pasture yield is inexpensive and fast, but untrained persons can give biased and unreliable estimates. One of the easiest, most affordable, and most reliable estimation options is using a grazing stick or pasture ruler. This publication outlines the procedures used for collecting data in field and calculating available forage for your farm. An additional author is Justin Burt, a postdoctoral research associate in the Department of Crop and Soil Sciences, University of Georgia Tifton Campus.

A good grazing management plan is essential to producer success for any grazing livestock production system. One of the keys to building a grazing management plan is to have a good understanding of the stocking rate on your farm and how this relates to forage availability. Stocking rate is a critical factor in all grazing operations, no matter the livestock species. By accurately determining stocking rate, understanding their grazing management options, and measuring forage availability producers can develop an effective grazing management plan for their operation.

This biennial publication contains the proceedings of the turfgrass field day carried out at the UGA Griffin campus every other year. The guide provides professionals with continuous, real-time access to the latest up-to-date information about turfgrass research studies, products, and turfgrass Extension activities, programs, and outreach. Topics will include, but are not limited to: crop and soil science, agronomy, weed science, plant pathology, entomology, economics, tissue culture, urban agriculture, irrigation, and student posters.

In 2010, the UGA cotton agronomists implemented this variety testing program. Our industry partners were asked to provide their most well-suited varieties for Georgia. Historically, the varieties evaluated in this trial have accounted for nearly 75% of the planted acreage in Georgia in the same year. These varieties were planted in replicated trials in growers’ fields throughout cotton-producing regions of Georgia, through coordination with the county Extension agents. The trials were managed and replicated by the grower with the assistance of the coordinating county agent to achieve realistic and statistically sound results.

La bermuda es una planta perenne de estación cálida ampliamente utilizada para su uso como césped en el sudeste de los Estados Unidos.
[Although improved common (Cynodon dactylon (L.) Pers.) and hybrid bermudagrasses (Cynodon dactylon x C. transvaalensis Burtt-Davy) have desirable qualities as turfgrasses for heat, drought and wear tolerance, bermudagrass is a problematic weed when grown in mixed stands with other turf species. Selective control of bermudagrass is difficult but often warranted in order to maintain acceptable quality of the desired turfgrass species. This publication describes bermudagrass control methods for Southern lawns.]

Annual bluegrass (Poa annua L.) is a problematic winter annual weed in residential turf. Compared to most turfgrasses, annual bluegrass has a lighter green color, coarser leaf texture and produces unsightly seedheads. Contrary to its name, both annual (live for one season) and perennial (live for many seasons) biotypes of annual bluegrass may be found in turf. This publication describes methods of control for annual bluegrass in residential turfgrass lawns.
